Elevate your Harley Davidson riding experience with the Jims 6-Speed Overdrive Super Gear Kit, specifically engineered for 1990-2000 FLSTF and FLSTC models. This comprehensive kit transforms your stock 5-speed transmission into a high-performance 6-speed unit, delivering enhanced power delivery and unparalleled cruising comfort.

Description

The Jims 6-Speed Overdrive Super Gear Kit is designed to significantly upgrade the drivetrain performance of your Harley Davidson Fat Boy FLSTF 1340 or Heritage Softail Classic FLSTC 1340 from 1990-2000. At its core, this kit features a 2.94:1 close-ratio 1st gear, which not only broadens your bike's usable speed range in first gear but also minimizes the RPM drop when shifting into second, resulting in smoother, more responsive acceleration. The inclusion of an overdrive 6th gear with a 0.86:1 ratio is a game-changer for long-distance riders, effectively lowering engine RPM by nearly 475 at 75 mph. This reduction in engine speed translates directly into a more relaxing cruising experience, less engine wear, and a noticeable decrease in vibration. Engineered to convert your existing 5-speed transmission into a modern 6-speed system, this Jims gear kit enhances both the performance and comfort of your ride. Built with precision and proudly Made in the USA, it includes all necessary gaskets and seals for a complete and reliable installation.
